The geologic quality factor Q inversion method is mainly to apply a logarithmic spectrum comparison method, a central frequency offset method and a peak frequency offset method, a scanning analysis technology and a time-frequency analysis combining method, and a multi-window analysis method on the amplitude spectrum of the seismic sub-wave. Among these, it is assumed in the central frequency offset method and the peak frequency offset method that the amplitude spectrum of the seismic wave can be represented by a Gaussian spectrum; and it is assumed in the time-frequency analysis method that the seismic sub-wave has a zero phase.
